• Each web page is represented as a separate class and all the elements on that page are defined as variables in that class.

• The methods in the class perform actions on those elements.

• It makes test scripts more readable and easier to mainta...read more

Annotations in TestNG are used to provide additional information about the test methods and classes.

• Annotations can be used to set the priority of a test method using @Test(priority = 1)

• Annotations can be used to group test methods using @Test(groups = {"smoke", "regression"})

• Annotations can be used to run a method before or after a test using @Before...read more

To inspect static and dynamic drop-down in Selenium, we can use the Select class and wait for the element to be visible.

• Use the Select class to interact with drop-downs

• For static drop-downs, locate the element and use the Select class to select the desired option

• For dynamic drop-downs, wait for the element to be visible before interacting with it

• Use the 'SelectBy' methods to select options by value, index, or visible t

TestNG allows setting priorities and grouping of test cases for efficient test execution.

• Use the 'priority' attribute to set the execution order of test methods.

• Use the 'groups' attribute to group test methods based on common characteristics.

• Use the 'dependsOnGroups' attribute to specify the order of group execution.

• Use the 'dependsOnMethods' attribute to specify the order of method execution.

• Use the 'enabled' attribut...read more
